Description

[Technical field]

[0001] The present invention relates to a component supplying device that conveys a carrier tape having a cover tape affixed to a base tape containing components, and supplies the components to a component removal position. [Background technology]

[0002] Conventionally, there is known a component supplying device that supplies the components to a component removal position by conveying a carrier tape in which a cover tape is affixed to a base tape that stores the components, and is generally referred to as a tape feeder. The tape feeder is configured to include a frame in which a carrier tape conveying path is formed and a conveying mechanism that conveys the carrier tape, and is configured to peel off the cover tape from the base tape before the carrier tape traveling on the conveying path reaches the component removal position, thereby enabling the components to be picked up at the component removal position.

[0003] Such tape feeders include manual tape set types in which an operator manually peels the cover tape from the base tape before setting the carrier tape in the transport path, as well as auto tape set types in which the initial peeling of the cover tape is performed automatically (see, for example, Patent Document 1 below). Regardless of whether it is the manual tape set type or the auto tape set type, the cover tape peeled from the base tape is sandwiched between multiple rollers prepared for discharging the cover tape and guided in the opposite direction to the transport direction of the carrier tape, and sent out to a cover tape discharge path formed in the frame.

[0004] [Patent Document 1] Patent Publication No. 2021-125625 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, as shown in the above Patent Document 1, some auto tape set type tape feeders can also be used as manual tape set type tape feeders. When using an auto tape set type tape feeder as a manual tape set type tape feeder, a preparatory work is required in which the cover tape is manually peeled off from the base tape and the leading end of the peeled cover tape is passed between multiple rollers for discharging the cover tape, but this work is not easy and takes a lot of time.

[0006] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a component supplying device that can quickly and easily carry out preparation work when using an auto tape set type tape feeder as a manual tape set type. [Means for solving the problem]

[0007] The component supplying device of the present invention is a component supplying device that transports a carrier tape having a cover tape affixed to a base tape storing components, and supplies the components to a component removal position, and includes a frame having a transport path for the carrier tape, a transport mechanism that transports the carrier tape along the transport path, a first roller and a second roller attached to the frame that capture the cover tape of the carrier tape transported by the transport mechanism and peel it off from the base tape, a third roller that sandwiches the cover tape captured by the first roller and the second roller and peels it off from the base tape, or the cover tape that has been manually peeled off from the base tape, between the first roller and the third roller, and sends it to a cover tape discharge path, and a roller support attached to the frame that supports the third roller, and is movable between a first position where the third roller sandwiches the cover tape between the first roller and the third roller, and a second position where the third roller is separated from the first roller.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting device 1 equipped with a tape feeder, which is an embodiment of a component supply device of the present invention. The component mounting device 1 is a device that mounts components BH on a board KB, and is equipped with a board transport unit 12 on a base 11. The board transport unit 12 transports the board KB horizontally and positions it at a predetermined work position. For the sake of convenience, the transport direction of the board KB by the board transport unit 12 is referred to as the X direction, the horizontal direction perpendicular to the X direction is referred to as the Y direction, and the up-down direction is referred to as the Z direction. In addition, in the Y direction, the direction toward the center of the base 11 is referred to as the "front", and the direction toward the opposite side is referred to as the "rear".

[0011] 1, a mounting head 13 is provided above a base 11. The mounting head 13 is moved in the horizontal direction by a head moving mechanism (not shown). The mounting head 13 is provided with a plurality of nozzles 14 extending downward.

[0012] In Fig. 1, a dolly 15 is connected to the end of base 11 in the Y direction. Dolly 15 is equipped with a feeder base 15a and a reel holding section 15b. Tape feeders 16 are detachable from feeder base 15a, and a plurality of tape feeders 16 are mounted on feeder base 15a in a line in the X direction. Reel holding section 15b rotatably holds reel RL around which carrier tape CT transported by tape feeder 16 is wound.

[0013] First, the carrier tape CT will be described. As shown in Figures 2(a) and 2(b), the carrier tape CT has a number of pockets PK for storing components arranged in a row, and a number of feed holes KH are arranged in a row parallel to the row of pockets PK.

[0014] 2(a) and 2(b), each pocket PK contains one component BH, and a cover tape TT is attached to the top surface of the carrier tape CT in a position that covers the pocket PK. In other words, the component BH is contained in the carrier tape CT covered by the cover tape TT.

[0015] As shown in Fig. 2(a), the leading portion of the cover tape TT is processed so as to extend beyond the leading end of the base tape BT by a certain length L. Hereinafter, the portion of the cover tape TT extending beyond the leading end of the base tape BT by the length L will be referred to as the "extending portion SD" of the cover tape TT (Figs. 2(a) and 2(b)).

[0016] 3, tape feeder 16 is configured with a frame 21 that is detachably attached to feeder base 15a as a base, and a transport path 21L that is a transport passage for carrier tape CT is formed within frame 21. A tape entrance 21A that is an entrance to transport path 21L is formed at the rear end of frame 21, and a tape exit 21B that is an exit from transport path 21L is formed at the front end of frame 21. The leading end of carrier tape CT pulled out from reel RL is inserted into tape entrance 21A.

[0017] A transport mechanism 22 is provided within the frame 21, which transports the carrier tape CT inserted from the tape inlet 21A along the transport path 21L. As shown in Fig. 3, the transport mechanism 22 includes three sprockets (inlet sprocket 22A, positioning sprocket 22B, and discharge sprocket 22C) aligned from rear to front, and a sprocket drive motor 22D. The sprocket drive motor 22D is operated under the control of a control unit 23 (Fig. 3) provided within the frame 21, and rotates the three sprockets in the same direction (clockwise in Fig. 3) via a gear mechanism (not shown).

[0018] 3, a plurality of feed pins 22P are provided on the outer periphery of each of the three sprockets (introduction sprocket 22A, positioning sprocket 22B, and discharge sprocket 22C). When these three sprockets are rotated by a sprocket drive motor 22D, the feed pins 22P of each sprocket engage with feed holes KH provided in the carrier tape CT from below, advancing the carrier tape CT on the conveying path 21L toward the tape exit 21B. At this time, the carrier tape CT is delivered in the order of introduction sprocket 22A, positioning sprocket 22B, and discharge sprocket 22C.

[0019] 3 and 4, a tape cover 24 is detachably attached to the upper part of the frame 21. The tape cover 24 covers from above a portion of the transport path 21L located between the positioning sprocket 22B and the discharge sprocket 22C.

[0020] 5, the tape cover 24 is composed of a single plate-like member, and the lower surface of the tape cover 24 has a shape that fits along the upper surface of the transport path 21L. The end portion on the rear end side of the tape cover 24 forms an inclined portion 24S that has a shape that is inclined so that the distance from the transport path 21L gradually increases toward the rear (upstream side).

[0021] 3, 4, and 5, a component removal position 16T is set at a position on transport path 21L between positioning sprocket 22B and discharge sprocket 22C. Component removal position 16T is a position where mounting head 13 removes component BH from carrier tape CT by nozzle 14. A component removal opening 24K is provided at a position directly above component removal position 16T in tape cover 24 (FIG. 5).

[0022] As described later, the cover tape TT is peeled off from the carrier tape CT before it reaches the component take-out opening 24K. Therefore, the pocket PK located at the component take-out position 16T by the transport operation of the carrier tape CT by the transport mechanism 22 becomes exposed upward directly below the component take-out opening 24K, and the mounting head 13 (nozzle 14) can take out the component BH through the component take-out opening 24K at the component take-out position 16T.

[0023] 4 and 5, a cover tape pull-out opening 24G is provided at a position slightly rearward (upstream side) of the component removal opening 24K of the tape cover 24. As will be described later, this cover tape pull-out opening 24G is an opening for pulling out the cover tape TT, which has been manually peeled off from the base tape BT, above the tape cover 24 when the tape feeder 16 is used as a manual tape set type.

[0024] 5, a sprocket avoidance hole 24H is provided at a position to the side of the cover tape pull-out opening 24G in the tape cover 24. The sprocket avoidance hole 24H is an elongated hole extending in the longitudinal direction (Y direction) of the tape cover 24. The sprocket avoidance hole 24H is provided to prevent interference between the feed pin 22P of the positioning sprocket 22B and the tape cover 24.

[0025] 5, a cover tape passage 24T is provided at a rearward position in the middle of the longitudinal direction (Y direction) of the tape cover 24. The cover tape passage 24T is made of a slit extending in the width direction (X direction) of the tape cover 24.

[0026] 3, 4 and 6 (FIG. 6 is an enlarged view of area RY in FIG. 4), air blowing unit 25 and three rollers (first roller 26, second roller 27 and third roller 28) are provided within frame 21. Air blowing unit 25 is provided at a position below cover tape passage 24T, and blows out air 25A from below tape cover 24 toward cover tape passage 24T.

[0027] 6, the first roller 26, the second roller 27, and the third roller 28 are located above the cover tape path 24T. In this embodiment, these three rollers are all made of gears. The second roller 27 and the third roller 28 each have a smaller diameter than the first roller 26, and each mesh with the first roller 26. The second roller 27 is located downstream of the first roller 26, and the third roller 28 is located above the first roller 26 (upstream of the second roller 27).

[0028] The first roller 26 is rotationally driven by a transmission gear mechanism (not shown) that transmits the power of the sprocket drive motor 22D. Therefore, the first roller 26 and the second roller 27 and third roller 28 meshed with the first roller 26 operate at a timing linked to the operation of the three sprockets (the entrance sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C) that transport the carrier tape CT.

[0029] The first roller 26 is driven to rotate in the counterclockwise direction in FIG. 6 (arrow R1 shown in the figure). The second roller 27 is rotated by the first roller 26 in the opposite direction to the first roller 26, i.e., the clockwise direction in FIG. 6 (arrow R2 shown in the figure). The third roller 28 is similarly rotated by the first roller 26 in the opposite direction to the first roller 26 (arrow R3 shown in the figure). Thus, in this embodiment, the second roller 27 and the third roller 28 are each configured to rotate in a counter direction between them and the first roller 26.

[0030] 3, 4 and 6, a roller support 31 is provided at the upper part of the middle part in the longitudinal direction (Y direction) of the frame 21. The roller support 31 is made of a block-shaped member extending in the Y direction as a whole.

[0031] One end (rear end) of the roller support 31 is attached to the frame 21 by a swing shaft 32 extending in the width direction (X direction) of the frame 21, and is movable (opened and closed) relative to the frame 21 by swinging about the swing shaft 32. In detail, the roller support 31 is movable (opened and closed) between a closed position (FIG. 7) in which the front end, which is the end opposite to the rear end attached to the frame 21, is located in front of the swing shaft 32 and is in a closed posture (closed posture) relative to the frame 21, and an open position (FIG. 8) in which the front end is located diagonally forward of the swing shaft 32 and is in an open posture (open posture) relative to the frame 21.

[0032] Thus, in this embodiment, the roller support 31 supporting the third roller 28 is freely movable between a closed position (first position) in which it is in a closed position relative to the frame 21, and an open position (second position) in which it is in an open position relative to the frame 21, and one end (rear end) is attached to the frame 21 by the swing shaft 32, and moves between the closed position (first position) and the open position (second position) by swinging around the swing shaft 32.

[0033] Of the first roller 26, the second roller 27, and the third roller 28, the first roller 26 and the second roller 27 are each attached to the frame 21. Meanwhile, the third roller 28 is attached to a roller support 31. When the roller support 31 is in the closed position (first position), the third roller 28 meshes with (contacts) the first roller 26 (FIGS. 6 and 7), and when the roller support 31 is in the open position (second position), the third roller 28 is spaced apart from the first roller 26 (FIG. 8).

[0034] 7 and 8, a long hole 33 is provided at the rear end of the roller support 31, penetrating the roller support 31 in the width direction (X direction) and extending along the longitudinal direction (Y direction), and the swing shaft 32 extends through the long hole 33. This allows the roller support 31 to move (slide) as a whole along the long hole 33. In Figures 6 and 7, a wall portion 34 is formed inside the roller support 31, and a biasing spring 35 made of a compression spring is provided between the wall portion 34 and the swing shaft 32.

[0035] 6, when roller support body 31 is in the closed position, the entire roller support body 31 is urged forward by urging spring 35, thereby pressing third roller 28 against first roller 26. That is, in this embodiment, urging spring 35 serves as urging means that urges third roller 28 in a direction pressing third roller 28 against first roller 26 when roller support body 31 is in the closed position.

[0036] 6, 7 and 8, a pair of protrusions 36 protruding outward in the left-right direction are provided on both left-right direction (X direction) sides of the front part of the roller support 31. In this embodiment, the pair of protrusions 36 extend on the same axis as the rotation shaft of the third roller 28.

[0037] 6, 7, and 8, hook-shaped engagement grooves 21M that open toward the rear are formed on the left and right sides of the upper middle part in the longitudinal direction (Y direction) of the frame 21. When the roller support 31 is in the closed position, the left and right protrusions 36 of the roller support 31 enter and engage with the left and right engagement grooves 21M provided on the frame 21 from the rear (FIGS. 6 and 7). In this state, the entire roller support 31 is biased forward by the biasing spring 35, the left and right protrusions 36 engage with the left and right engagement grooves 21M, and the roller support 31 is locked in the closed position.

[0038] In this embodiment, when the roller support 31 is in the closed position (first position), the roller support 31 is locked to the frame 21 by the biasing force of the biasing spring 35 which biases the third roller 28 in the direction of pressing the third roller 28 against the first roller 26.

[0039] To move the roller support 31 from the closed position to the open position, first, the roller support 31 is pressed backward with a finger (i.e., toward the swing shaft 32). This pressing causes the roller support 31 to move backward as a whole while compressing the biasing spring 35 (FIG. 9(a) → FIG. 9(b)), and the left and right protrusions 36 of the roller support 31 are released from the left and right engagement grooves 21M formed in the frame 21 (FIG. 9(b)).

[0040] When the left and right protrusions 36 are released from the left and right engagement grooves 21M, the roller support 31 is unlocked from the frame 21. If the front end of the roller support 31 is then pushed upward and rearward with a finger (FIG. 9(b) → FIG. 9(c)), the roller support 31 will swing around the swing shaft 32 and assume the open position (FIG. 9(c)).

[0041] In this embodiment, when the roller support 31 is positioned in the closed position (first position), moving the third roller 28 in a direction away from the first roller 26 against the force of the spring 35 releases the lock of the roller support 31 from the frame 21.

[0042] To move the roller support 31 from the open position to the closed position, first press the roller support 31 with a finger toward the swing shaft 32 and move the front end of the roller support 31 in that state downward (Fig. 9(c) → Fig. 9(b)). As a result, when the left and right protrusions 36 are positioned behind the left and right engagement grooves 21M, release your finger from the roller support 31. When you release your finger from the roller support 31, the roller support 31 as a whole is urged forward by the urging spring 35 (Fig. 9(b) → Fig. 9(a)), so that the left and right protrusions 36 engage with the left and right engagement grooves 21M from behind, and the roller support 31 is positioned at the closed position and locked to the frame 21 (Fig. 9(a)).

[0043] 7, 8 and 10, a guide portion 41 is provided on the downstream side of the first roller 26. The surface of the guide portion 41 facing the first roller 26 (guide surface 41M) extends in an arc shape along the outer circumferential surface on the front side of the first roller 26, as shown in Fig. 10 (see also Figs. 9(a), (b) and (c)).

[0044] 4, 6 and 10, a partition member 42 is provided between the transport path 21L and the roller support 31. The partition member 42 has a shape extending in the front-rear direction (Y direction) of the frame 21, and divides the space between the transport path 21L and the roller support 31 in the frame 21 into upper and lower parts. The meshing portion of the first roller 26 and the third roller 28 faces the downstream side of the space formed between the partition member 42 and the roller support 31 positioned in the closed position, forming a cover tape discharge path 21J through which the cover tape TT is discharged.

[0045] Next, the supply operation of the parts BH by the tape feeder 16 through the automatic tape setting will be described. When the tape feeder 16 is made to supply the parts BH, the worker first forms the above-mentioned extension portion SD of the cover tape TT at the leading portion of the carrier tape CT. After forming the extension portion SD of the cover tape TT, the worker inserts the leading portion of the carrier tape CT into the tape inlet 21A. Then, the carrier tape CT is pushed downstream until the feed hole KH near the leading portion of the carrier tape CT engages with the feed pin 22P of the introduction sprocket 22A.

[0046] When the operator presses in the carrier tape CT, the feed hole KH near the leading end of the carrier tape CT hits the feed pin 22P of the lead-in sprocket 22A, and the carrier tape CT stops just before engaging with the feed pin 22P. Then, when an operation switch (not shown) is operated, the control unit 23 operates the sprocket drive motor 22D to rotate the three sprockets (the lead-in sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C). This causes the carrier tape CT on the transport path 21L to start moving toward the tape exit 21B.

[0047] The leading edge of the carrier tape CT traveling on the transport path 21L abuts against the inclined portion 24S at the rear end of the tape cover 24 from behind, and while pushing up the entire tape cover 24, enters between the tape cover 24 and the transport path 21L (FIG. 10 → FIG. 11). As described above, the inclined portion 24S of the tape cover 24 has a shape in which the distance from the transport path 21L gradually increases toward the rear (upstream side), so that the leading edge of the carrier tape CT can smoothly enter between the tape cover 24 and the transport path 21L.

[0048] When the leading end of the carrier tape CT enters between the tape cover 24 and the transport path 21L, the control unit 23 causes the air blowing unit 25 to blow air 25A (FIG. 11). As a result, the leading end of the extension portion SD of the cover tape TT is blown upward, and is guided to move through the cover tape passage 24T to above the tape cover 24 (i.e., above the base tape BT) (FIG. 11).

[0049] The extension portion SD of the cover tape TT that has moved above the tape cover 24 through the cover tape passage 24T has its leading end pinched (captured) and pulled up by the first roller 26 and second roller 27, which rotate in opposite directions (FIG. 12). As described above, the second roller 27 of the first roller 26 operates at the same timing as the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C), so the lifting up of the cover tape TT by the first roller 26 and the second roller 27 is performed in conjunction with the advancement of the carrier tape CT. Therefore, thereafter, the cover tape TT is peeled off from the base tape BT in accordance with the advancement of the carrier tape CT.

[0050] Thus, in this embodiment, air blowing unit 25 functions as a guiding means for guiding extension portion SD of cover tape TT, which is formed so as to protrude from the leading end of base tape BT on conveying path 21L at a position upstream of component removal position 16T, to above base tape BT. Also, first roller 26 and second roller 27 rotate while sandwiching (capturing) extension portion SD of cover tape TT, which is guided above base tape BT by guiding means (air blowing unit 25), to form peeling portion HB that pulls up cover tape TT and peels it off from base tape BT (FIGS. 4 and 6).

[0051] The cover tape TT, which has been pulled up by the first roller 26 and the second roller 27 and peeled off from the base tape BT, is guided by the guide surface 41M of the guide portion 41 and moves backward in an arc along the outer circumferential surface of the first roller 26 (FIG. 12). The cover tape TT is then sandwiched between the first roller 26 and the third roller 28, which rotate in opposite directions, and transported backward (upstream), and sent out to the cover tape discharge path 21J described above (FIGS. 13-14).

[0052] Thus, tape feeder 16 in this embodiment is configured to include first roller 26 and second roller 27 that capture the cover tape TT of carrier tape CT transported by transport mechanism 22 and peel it off from the base tape BT, and third roller 28 that sandwiches the cover tape TT peeled off from the base tape BT between first roller 26 and sends it to cover tape discharge path 21J. In this embodiment, first roller 26 and third roller 28 function as "two rollers for discharging the cover tape."

[0053] As described above, the tape feeder 16 performs a conveying operation to convey the carrier tape CT by the conveying mechanism 22, while simultaneously performing a peeling operation to peel the cover tape TT from the base tape BT. Since the position at which the cover tape TT is peeled off from the base tape BT is a position upstream of the component removal position 16T, the components BH stored in the carrier tape CT (base tape BT) continue to be uncovered by the cover tape TT after the cover tape TT is peeled off until they reach the component removal position 16T, but instead are covered from above by the tape cover 24, so they remain contained within the pocket PK of the base tape BT.

[0054] When the component BH stored in the carrier tape CT reaches the component removal position 16T, it is exposed upward through the component removal opening 24K of the tape cover 24. This allows the component mounting device 1 to suck and remove the component BH through the component removal opening 24K with the mounting head 13 (nozzle 14) (FIG. 14).

[0055] In this manner, the tape feeder 16 in this embodiment is an auto tape set type tape feeder that transports the carrier tape CT having the cover tape TT affixed to the base tape BT containing the component BH, and captures the cover tape TT with the first roller 26 and the second roller 27 at a position before (upstream) the component removal position 16T and automatically peels it off from the base tape BT, thereby supplying the component BH to the component removal position 16T.

[0056] When component mounting device 1 having tape feeder 16 of the above configuration as a component supplying device performs a component mounting operation of mounting components BH onto board KB, first, board KB is supplied from outside component mounting device 1. After board KB is supplied, board transport section 12 operates to carry in board KB and position it at a predetermined work position. After board transport section 12 positions board KB at the work position, each tape feeder 16 starts a component supplying operation to continuously supply components BH to component removal opening 24K.

[0057] When each tape feeder 16 starts its component supplying operation, the mounting head 13 uses the nozzle 14 to pick up and remove the component BH that the tape feeder 16 supplies to the component removal position 16T. After removing the component BH from the tape feeder 16, the mounting head 13 moves to above the board KB and mounts the component BH at the target component mounting position determined on the board KB.

[0058] Once the mounting head 13 has mounted all of the components BH to be mounted on the board KB as described above, the board transport unit 12 operates to transport the board KB out of the component mounting device 1. This completes the component mounting operation for one board KB.

[0059] The tape feeder 16 in this embodiment is used as an automatic tape set type as described above, but can also be used as a manual tape set type that performs the supply operation of the parts BH without the process of capturing the cover tape TT by the first roller 26 and the second roller 27. In this case, the worker manually pulls out the cover tape TT, which has been peeled off from the base tape BT, rearward from the cover tape pull-out opening 24G, and then manually clamps it between the two rollers (the first roller 26 and the third roller 28) for discharging the cover tape.

[0060] When the operator sandwiches the cover tape TT pulled out rearward from the cover tape pull-out opening 24G between the two rollers (the first roller and the third roller) for discharging the cover tape, the operator first positions the roller support 31 in the open position in the manner described above (FIG. 9(a)→FIG. 9(b)→FIG. 9(c)), and separates the third roller 28 from the first roller 26 (FIG. 15). After separating the third roller 28 from the first roller 26, the operator then positions the leading end of the cover tape TT above the first roller 26 (FIG. 16(a)). Then, the operator presses the roller support 31 toward the swing shaft 32 against the biasing force of the biasing spring 35 (arrow P shown in FIG. 16(a)), and while maintaining the pressed state, swings the roller support 31 around the swing shaft 32 (FIG. 16(a)→FIG. 16(b)).

[0061] When the roller support 31 is swung so that the left and right protrusions 36 of the roller support 31 are positioned behind the two engagement grooves 21M formed in the frame 21 (FIG. 16(b)), the operator releases his / her fingers from the roller support 31 to release the pressure on the roller support 31. When the operator releases his / her fingers from the roller support 31, the roller support 31 moves forward due to the biasing force of the biasing spring 35, and the left and right protrusions 36 engage with the left and right engagement grooves 21M (FIG. 16(b) → FIG. 16(c)). This positions the roller support 31 in the closed position and locks it to the frame 21 (FIG. 16(c)).

[0062] When the roller support 31 is located at the closed position as described above, the cover tape TT, whose leading portion is located above the first roller 26, is sandwiched between the two rollers (the first roller 26 and the third roller 28) for discharging the cover tape. In this embodiment, when the roller support 31 is located at the open position (the second position), the third roller 28 moves away from the first roller 26, and when the roller support 31 is located at the closed position (the first position), the third roller 28 sandwiches the cover tape TT between itself and the first roller 26. When the cover tape TT is sandwiched between the two rollers (the first roller 26 and the third roller 28) for discharging the cover tape, the preparation work for using the tape feeder 16 as a manual tape set type is completed.

[0063] After completing the preparation work for using tape feeder 16 as a manual tape set type, control unit 23 operates transport mechanism 22, whereby the carrier tape CT is transported by three sprockets (introduction sprocket 22A, positioning sprocket 22B, and discharge sprocket 22C), and the two rollers (first roller 26 and third roller 28) for discharging the cover tape also rotate in conjunction with the rotation. As a result, the cover tape TT is peeled off in conjunction with the transportation of the carrier tape CT, and the peeled cover tape TT is sent out to cover tape discharge path 21J by the two rollers (first roller 26 and third roller 28) for discharging the cover tape (FIG. 17).

[0064] In this embodiment, when the tape feeder 16 is used as an automatic tape set type, the third roller 28 sandwiches the cover tape TT captured by the first roller 26 and the second roller 27 and peeled off the base tape BT between the first roller 26 and the third roller 28, and sends it to the cover tape discharge path 21J, and when the tape feeder 16 is used as a manual tape set type, the third roller 28 sandwiches the cover tape TT manually peeled off the base tape BT between the first roller 26 and the third roller 28, and sends it to the cover tape discharge path 21J. That is, the third roller 28 sandwiches the cover tape TT captured by the first roller 26 and the second roller 27 and peeled off the base tape BT, or the cover tape TT manually peeled off the base tape BT between the first roller 26 and the third roller 28, and sends it to the cover tape discharge path 21J.

[0065] In the tape feeder 16 of the present embodiment, the first roller 26 and the second roller 27 are attached to the frame 21, while the third roller 28 is attached to the roller support 31. Therefore, when used as a manual tape set type, the operator need only position the roller support 31 in the open position, then position the leading end of the cover tape TT, which has been manually peeled off from the base tape BT, between the first roller 26 and the third roller 28, and then swing the roller support 31 to position it in the closed position, and the preparation work can be completed easily and in a short time.

[0066] As described above, in the auto tape set type tape feeder 16 in this embodiment, the first roller 26 is attached to the frame 21, while the third roller 28 is supported (attached) by the roller support 31, and the roller support 31 is movable between a first position (closed position) where the third roller 28 and the first roller 26 sandwich the cover tape TT, and a second position (open position) where the third roller 28 is separated from the first roller 26. Therefore, the operation of sandwiching the cover tape TT between the two rollers for cover tape discharge can be performed simply by moving the roller support 31, which is located at the second position, to the first position. Therefore, according to this embodiment, the preparation work required when using the auto tape set type tape feeder 16 as a manual tape set type can be performed quickly and easily.

[0067] Although the embodiment of the present invention has been described so far, the present invention is not limited to the above, and various modifications are possible. For example, in the above embodiment, the biasing means for biasing the third roller 28 in the direction of pressing the third roller 28 against the first roller 26 when the roller support 31 is in the first position (closed position) is made up of a spring member (biasing spring 35) as an elastic member, but the biasing means may be made up of an elastic member other than a spring member (such as a rubber member).

[0068] Moreover, the roller support 31 may be configured to support the third roller 28 and to be movable between the first position and the second position. Therefore, instead of the configuration in which one end (rear end) of the roller support 31 is attached to the frame 21 by the swing shaft 32 extending in the width direction (X direction) of the frame 21 as in the above-mentioned embodiment, one end side in the left-right direction of the roller support 31 may be attached to the frame 21 by a swing shaft extending in the longitudinal direction (Y direction) of the frame 21. Alternatively, the roller support 31 may be configured to be movable between the first position and the second position by moving vertically in parallel with the frame 21. [Industrial Applicability]
